MATERIAL FOR REFLECTIVE MATERIAL AND REFLECTIVE MATERIAL USING THE SAME
To provide a low-emissivity material with high heat resistance and high oxidation resistance.SOLUTION: A material for reflective material of the present invention comprises a porous ceramics, in which the porous ceramics is composed of ceramic particles having an average particle size of 1 μm or more and 6 μm or less, and 40% or more of the ceramic particles have a particle size of 1 μm or more and 5 μm or less. An emissivity of the material for reflective material based on Kirchhoff's law in a wavelength range of 0.25 μm or more and 2.5 μm or less is 0.03 or less at 2000 K or more and 4000 K or less, and 0.06 or less at 4000 K or more and 6000 K or less is preferred.SELECTED DRAWING: None
【課題】高耐熱かつ高耐酸化性を持つ低放射率材料を提供する。【解決手段】本発明の反射材用材料は、多孔質セラミックスからなり、前記多孔質セラミックスは、平均粒子径１μｍ以上６μｍ以下のセラミックス粒子で構成され、かつ、前記セラミックス粒子の４０％以上を粒子径１μｍ以上５μｍ以下の粒子が占める。前記反射材用材料の波長０．２５μｍ以上２．５μｍ以下の範囲におけるキルヒホッフ則に基づく放射率は、２０００Ｋ以上４０００Ｋ以下で０．０３以下であり、４０００Ｋより大きく６０００Ｋ以下で０．０６以下であることが好ましい。【選択図】なし
